PROCESS OF WIRE-TYING AND PACKAGING BAGS.

Specification of Letters Patent.

Patented Feb. 1, 1916.

Application filed September 8, 1913. Serial No. 788,516.

Figure 1 is a view of two sections of wire. Fig. 2 a, view of the same,with one end of each twisted together. Fig. 3 a view of the same withthe twisted ends inwardly turned. Fig. 4 a view of the parts as arrangedin Fig. 3, with the gathered end of the bag in position. Fig. 5 is aview of the parts after the tie has becn'tightened. Fig. 6 is a view ofthe end of the wires after the tie has been'severed. Fig. 7 is a sideview of the tie in position on the bag after it has been severed fromthe wires. Fig. 8 is a view of a. series of bags, illustrating themanner in which the loop key is forced into position when the bags arearranged so as to be gathered in packages. 7

Like partsare indicated by the same letters.

The drawings are roughly diagrammatic and intended to be suggestiverather than descriptive of the several steps in the process.

-A and B are the ends of two wires. They may each be derived from a.coil. C represents the two ends of suchwires twisted together and Cindicates such twisted ends forced inwardly.

D are the gathered ends of the bags E.

F is a portion of the two wires at the point where they are twistedtogether.

G isthe key loop. G are the twisted ends of the wires after they aresevered,.projecting from and RSS() .ciated'with the key loop G. G showsthese twisted ends turned in toward the center of.

J is a platform or chute of any kind or description.

K are bars supporting, in any desired manner and of any desired shape,but so as to engage the gatheredends of thebags and hold them.

M illustrates the key 100 and its associated parts bent into paral elismwith and among the folds of the gathered bag end by contact with thenext succeeding bag.

In wire-tying bags, it is highly impor-- tant that there be no scraps orpieces of wire or loops of wire about'the premises." They aretroublesome, expensive to handle andinjurious in many ways. a.considerable loss of wire and if, loops are formed, their manufactureand use involves another operation or series of operations. My processtherefore begins with the use Their use entails of two coils of wire andI make a series of bag ties from their two ends. The free ends of thewires are first n some manner twisted as indicated in Figs. 2 and 6, andthey are then turned inwardly toward, but preferably not parallel withthe strands of. wire, v

and they may be brought into the position indicated by dotted lines inFig. 7. The-two wires are held so as to be'taut and the gath cred end ofthe bag is then brought in between the two wires and forcedinto theposition indicated in Fig. 4. A proper manipulation of the parts willbring the twisted end in between the folds, or if desired, it 1 may bemade to penetrate the fabric of the bag so these parts will be in theposition'in dicated in Figs. 4 and 7. The two strands of wire beyond butnear the bag are now twisted preferably so as to form a key loop,

as indicated in Fig. 5, and the twisting process is continued until thetie is sufii- 9c ciently tightened about the bag end and if a key loophas been formed, the parts will assume the position shown in Fig. 5. Thewires are then severed somewhere along the twisted portion between thestrands and the key loop, as indicated with a. dotted line in Fig. 5.This leaves the severed parts in the relation indicated respectively inFigs.- 6

and 7, but the part C of Fig. 6 mustno'w be bent into the positionindicated by C in Fig. 3. The projecting end or key loop of the tie maynow be forced up into; or parallel with the folds of the gathered endof.

the bag in any desired manner, but. this'maylpreferably be done inconnection with packaging the bags, or the bags maybe arranged betweenguide bars, held together in any suitable manner, as indicated in Fig.8, and

- gathcredforpickaging. By working this end . endsinwardly towardprocess, and it maybe done by hand or any desired -mecha,nism,'the firstformed twisted penetratesbetweenthe folds or into the fabric of thebag,so that it cannot injure objects coming in contact with the end of thebag, it cannot be untwisted, and it prevents the tie from being slippedoff the end of the bag. Such a process 'for tying a bag re: its also infurnishinga key loop with a protected end, because the end is within theloop and pa rallel with the wire which forms the loop. The key loopitself is entirely out of a position where it may come in contact withother objects, because it lies up around and more or less buried amongthe folds of the bag.

The several steps of manipulation may of course be varied withoutdeparting from the spirit of my invention, and the particular form andshape of the tie is not essential.
